Modern measurement systems often operate with single 5-V power supplies, yet their input signals may have large common-mode voltages that exceed the supply by tens or hundreds of volts...
Using a blue LED can pose problems when available power-supply voltages don't meet or exceed the LED's 3 V forward-voltage drop. This Design Idea shows how to drive a blue LED from a 3 V battery...
In the automotive industry, in which the goal is to produce cars with simpler, lighter wiring looms, any interface that uses just one wire instead of two offers a distinct advantage...
Anemometers are an important category of environmental sensor. Articles about their design, data capture, and linearization have comprised topics featured in EDN Design Ideas, several quite recently. Less well covered, however, has been the topic of accurate, inexpensive, (even improvisational) methods for their testing and calibration...
Many precision test-and-measurement and high-speed analog applications require an exact targeted voltage to be delivered to the device under test or intended load to accurately analyze the device...
The challenge of improving analog/digital accuracy by preventing amplifier saturation in systems supplied with only a single logic-level power rail has been receiving a lot of activity and design creativity recently...
AC loads are everywhere around us because at least home appliances are supplied with the mains power. Therefore, we always face the situations that we want to have full control (dimming) over an AC load such as a lamp, a motor, vacuum cleaner...
Despite massive, large-scale integration being ubiquitous in contemporary electronic design, discrete MOSFETs in the classic CMOS totem pole topology are still sometimes indispensable...
It’s common for I2C systems to have both standard and fast devices on the same bus. For I2C systems, the speed and power consumption both depend on the values of pullup resistors...
